Is there a dot after doctor?
British usage favours omitting the full stop in abbreviations which include the first and last letters of a single word, such as Mr, Mrs, Ms, Dr and St; American usage prefers (A) Mr., Mrs., Ms., Dr. and St., with full stops. Most other abbreviated titles, however, require a full stop, as shown above.
Putting periods after abbreviations (or not) is a little-known difference between British English and American English. British writers, however, make a distinction: abbreviations that are written with the first and last letter of the word (as in Dr. for Doctor and Mr. for Mister) do not get a period.
- MD: Abbreviation for the Latin title Medicinae Doctor, Doctor of Medicine. All medical schools in the United States and Canada award an M.D. degree, usually after 4 years undergraduate study at a college or university followed by 4 years of medical school.
- When you end a sentence with an abbreviation, you don't need an extra period. The period that ends the abbreviation also ends the sentence. Think of it as an environmentally friendly rule—one dot of ink serves two purposes.
- If only part of the sentence is parenthetical, then you put the final punctuation outside of the parenthesis: I enjoy breakfast (sometimes). If the entire sentence is parenthetical, then you put the punctuation inside the parenthesis.
Style Guide. Finally, there's no strict rule about putting periods after each letter in an acronym or initialism. Some publications put periods after each letter, arguing that because each letter is essentially an abbreviation for a word, periods are necessary.
- Associated Press Style is used for the listing of locations. Use the abbreviations Ave., Blvd. and St. with a numbered location: 2210 Wilbur Ave. Spell them out and capitalize when part of a formal street name without a number: Wilbur Avenue. All similar words—alley, drive, road, terrace—are always spelled out.
